Title: Biomembrane permeability modification by magnetic field pulser - employs miniature battery pivoted by resilient arm into contact with metallisation of circuit board carrying coil without iron core
Inventor: LANDWEHR ANDREAS
IPC: A61N2/04
Filed: 1992-09-21
Abstract: Within its housing (1) an arm (3) carrying a battery (2) is pivotable about an axis (4) either by pressure (5) on one end or by insertion of a fingernail into a slot (6). A resilient arm (8) fixed centrally to a circuit board (7) projects into the vicinity of the battery. The coreless winding is pulsed by a Schmitt trigger circuit at about 12 Hz so as to modify the membrane permeability by the influence of the rate of variation of magnetic flux density.

Patent DE-4313817-A1 (DE)
Title: Seal arrangement
Inventor: ANDERBERG GOERAN
IPC: F16J15/02
Filed: 1993-04-27
Abstract: The invention specifies an hygienic seal arrangement on bushing shafts which has a cover. The seal arrangement is intended, for example, for the food industry or the like. An outer sealing ring and an inner sealing ring are connected adhesively with the cover, for example by means of vulcanisation. In the arrangement, the side of the outer sealing ring which faces the medium to be sealed off is somewhat compressed, in that, in each case, the contact faces in the cover and in the wall in which the cover is arranged are of a shape converging in the direction of the medium side. The inner sealing ring in the form of a lip seal bears against part of a bushing shaft, the part being capable of moving somewhat to and fro, but not being capable of rotating. The lip seal is designed in such a way that the edge of the lip is pressed against the bearing face by the pressure of the product.

Title: Arrangement of individual pictures
Inventor: KAPITZ CARL-HEINZ
IPC: G09F19/22
Filed: 1993-05-07
Abstract: An efficient arrangement is proposed for individual pictures (2 to 5) along the line (1) of railbound vehicles (10), in particular underground trains or local trains, by means of which there can be conveyed to a viewer a temporal development in the form of a change in the picture information. For this purpose, the individual pictures (2 to 5) are arranged essentially at the level of the vehicle windows (6). According to the invention, the individual pictures (2 to 5) form a picture sequence. In addition, the spacings (7) between adjacent individual pictures (2 to 5) are matched in the individual sections of the line (1) to the expected speed (velocity) (v) of the railbound vehicle (10) in such a manner that a viewer is provided with the impression of a picture whose picture information changes with time. <IMAGE>

Title: Burner
Inventor: BOMBIS DIETER
IPC: F23D11/00
Filed: 1993-05-15

Patent DE-4407733-A1 (DE)
Title: Engine piston
Inventor: ARAI TAKAYUKI
IPC: F02F3/00
Filed: 1994-03-08
Abstract: Piston which can slide freely in an engine cylinder, the piston comprising a piston head of circular cross-section, a skirt which is formed in such a way that it is continuous towards the piston head, a gudgeon pin which passes through the skirt, and a piston rod which is connected to this gudgeon pin. The skirt comprises a top part and a bottom part, which each have a cross-section in the form of an ellipse, the short axes of the ellipse being parallel to the gudgeon pin. The cross-section of the ellipse of the top part has greater eccentricity than that of the bottom part. In addition, the skirt has a bevelled surface which forms a smooth transition between the top and bottom parts of the skirt. The contact surface between the skirt and the cylinder therefore has an inverted T-shape so that the contact surface of the bottom part of the skirt can be increased. It is therefore possible to set the distance from the centre of the gudgeon pin to the bottom edge of the skirt in such a way that it is not greater than 1.8 times the distance from the centre of the gudgeon pin to the top edge of the skirt, as a result of which the piston becomes more compact, while it retains its operating stability.

Abstract: The premagnetised region of the data carrier e.g. magnetic stripe card is partially or totally erased by the magnetic field produced by an impulse or surge current in a conductor.The erased region is evaluated quantitatively and qualitatively by a card reader and compared with a set of reference curves of defined erase profiles, including one which corresponds to the actual premagnetisation curve of the card, and others corresponding to defined surge currents. The reader gives a negative indication when the actual erasure curve does not correspond to the reference pattern. If it does match a reference curve, the corresponding surge current is displayed.

Title: Radar equipment
Inventor: FUKUHARA HIROSHIGE
IPC: G01S17/931
Filed: 1994-06-28
Abstract: A cheap, compact radar equipment measures the range to a target and the relative speed of the target. The apparatus has a transmitter for transmitting a pulsed signal and a receiver for receiving a pulsed signal which is reflected by the target. The received signal is converted into a binary signal which is sampled by a sampler and is accumulated in a cumulative memory unit. The addresses of the memory unit correspond to an interval between the transmission and the reception of the pulsed signal. The range and the relative speed of the target are calculated, at high speed, on the basis of the interval. The apparatus carries out a large number of accumulation operations, as a result of which the signal to noise ratio is improved and a weakly reflected signal can be quickly detected. <IMAGE>
